The paper highlights the research conducted in order to assess the effect of different doses of thyme extract on the productive properties and livability of broiler chickens. The experiment was conducted at a broiler poultry farm with a closed production cycle; the experiment assumed the control group and 5 experimental groups where each group contained 37 broilers at floor housing. The broilers of the 1st experimental group were fed with the extract of medicinal plant thyme dosed 2 mg/kg; broilers of the 2nd group received thyme extract dosed 4 mg/kg; 3rd group of broilers – 6 mg/kg, 4th group -8 mg/kg, and the dosage of the thyme extract was 10 mg/kg for broilers in the 5th experimental group. The authors controlled the live weight of broilers in each group by means of individual weighing every 7 days. Using this data the researchers calculated average daily body weight gain, absolute and relative gain; feed consumption was daily calculated. Feed consumption became the basis for calculating feed costs per a kilo of live weight gain. The authors recorded the number of daily fallen chickens. The data on poultry loss was the basis for calculating poultry livability. In order to assess production efficiency, the European productivity index was calculated. The research results indicate the efficiency of thyme extract application in different doses when feeding the broiler. Application of thyme extract in feeding meat poultry allowed to increase productive properties of broilers from experimental groups from 2.3 to 4.7%, reduce feed costs per a kilo by 1.1-8.1%, increase poultry livability on 2.7-8.1% and increase the European productivity index in the experimental groups on 0.2 21.3%.

The reaction of the organism of broiler ducklings to the introduction of the probiotic additive "Lactobifadol" into the organism when reared up to 7 weeks of age was investigated. A positive effect was achieved to increase the live weight of the experimental poultry by 5.0 % (p <0.5), the average feed consumption per 1 kg of live weight gain in the group of broiler ducklings fed with Lactobifadol feed was 4.7 % less when compared to intact poultry. The dynamics of feed consumption per 1 kg of live weight gain in the first three weeks of rearing was descending, and from 4 weeks of age until the end of rearing, fodder consumption increased significantly. For 6 weeks of growing, the average consumption of compound feed per head per day in the control group of broiler ducklings was 157.5 g, in the experimental group – 158.5 g per 1 bird/day. The inclusion of "Lactobifadol" in the diet to a certain extent stimulates the processes of erythrocytopoiesis, providing, within the physiological norm, an increase in the level of hemoglobin and the number of leukocytes.

The purposes of determining the influence of the light and sexing on growth performance and slaughter results atyoung quails from Balotesti population, was organized an experiment on 150 quails, betwen age of 28 and 70 days. The chicks were divided into two groups (control and experimental), and growth and slaughter performance were determined separately by sex. Have studied 2 lighting programs, a program of continous lighting with photoperiod duration of 16 hours (16 L + 8 N, control group) and a program with lighting with asymetric hours intervals with photoperiod duration of 16 hours (10L+2N+6L+6N, experimental group).Males and females from the experimental group were recorded average performance of growth high during the period 28 - 70 days. Live weight at age of 70 days was higher with 7.54 %, average weight gain was higher with 14.86 % and feed conversion rate was lower with 13.51 % at males from experimental group compared to males from the control group. Also, the live weight at the age of 70 days was higher with 18.09 %; average weight gain was higher with 35.12 %, while feed conversion rate was reduced with 30.08 % on females from the experimental group compared to females from the control group.The results of the slaughter at 70 days were superior in the caseof females from the both groups versus males. The average weight of the carcase was higher with 17.53 % in case of the females than that of males from the experimental group, and the carcase yield was 65.37 % at the females and 65.56 % for males. Also, the average weight of the carcase was higher with 5.08 % in case of females compared to that males from the control group, and the carcase yield was 64.20 % to females 66.70 % on males.Superior results recorded in the case of females and males from the experimental group recommended the program of lighting with asymmetric hours intervals in the growth of youth quail. Also, the higher slaughter results recorded in the case of females of the two groups recommended them in the meat production through a broiler of quail that combine advantages in the production of both males and females.

The feeding effect of polyacrylamide (PA), mineral and vitamin additives (MVA) on the reproductive and productive qualities of sows, as well as the development and viability of piglets gained from them has been studied. The polyacrylamide, mineral and vitamin additives have been added to the sow diet of the 2nd and 3rd experemental groups. It has been done according to the animal need in minerals and vitamins. In proportion of 0,5/1 kg of live weight, the mineral and vitamin aditives, polyacrylamide have been added to the ration of sows from the 2nd experimental group. The mineral and vitamin aditives have been added to the ration of the 3rd group in such proportion: iron sulfate – 200, copper carbonate – 15, zinc – 84, cobalt – 3, manganese chloride – 69, potassium iodide (stabilized) – 170 mcg, vitamins A – 2.8 th. IO, D – 736 IO, B1 – 1.4 mg; B2 – 8.4 micrograms per head per day. The mineral and vitamin additives, polyacrylamide have been added to the sow diet of the 4th experimental group in the same proportion as it has been already mentioned above. The sows fed on PA and MVA for 60 days. The feeding was stopped 10 days before farrowing. The experiment on piglets has been carried out in 2 stages. The equalization period was 25 days (the ration of piglets from the control and experimental group was the same). The main period was 150 days (the control group of animals fed on standard compound fodder). The experimental group fed on additional PA and MVA. It has been noticed when the additives are added to the sow diet the gained piglets have an increase of viability, immun response (due to gamma globulins increase in blood proteins) and the average live weight by 23.3% during the rising period.

In order to increase the meat productivity of broiler chickens, increase production volumes and reduce the prime-cost of poultry products, it is necessary not only to ensure balanced feeding and compliance with production technology but also to include in the poultry diet non-traditional additives, biologically active substances that contribute to the normalization of metabolic processes and improve the digestibility of feed nutrients. One of these dietary additives is Betulin extracted from birch bark, which has antioxidant and immunomodulatory properties. In this regard, the purpose of the research was to study the influence of compound feed with the introduction of 2 % feed additive based on a synthetic microspherical nanoporous carbon carrier containing biologically active Betulin in its composition on the productivity of broilers. The results of studies on broiler chickens using compound feed with 2 % feed additive have been presented in the article. It has been found that the feed consumption per 1 kg of live weight gain in poultry of the experimental group have been lower by 9,5 % due to better absorption of nutrients, the live weight of broiler chickens of the experimental group at the age of 42 days was 2625,6 g and it was higher than the control group by 3,68 %. The digestibility of crude protein and fat reached 92,73 and 88,03 %, which exceeded the control group by 1,03 and 3,03 abs.%, respectively. It has been found that the use of compound feed with 2 % of the feed additive with the biologically active substance is of practical importance in connection with the increase in the productivity of broilers and the level of profitability of meat production by 8,2 abs.%.

The reliability of the results obtained in scientific and economic experiments on the study of the effectiveness of the use of various feed components, including biologically active substances in the rearing of broilers needs to be confi rmed in production conditions. The purpose of the research was to study the joint use of enzyme drugs and lecithin in the rearing of broiler chickens. The results of production experiment on the study of the effectiveness of the joint inclusion of enzyme drugs Sunzyme and Sunfyse 5000 as well as lecithin in the diet of broiler chickens of the cross Ross-308 have been presented in the article. Production tests have been carried out under the conditions of the breeding farm “Achkhoy– Martanovsky” in the Chechen Republic. The duration of the experiment was 45 days. For research on the principle of analog groups two groups have been formed: a control group and an experimental group of 1000 heads in each. The broilers of the control group have been fed compound feed prepared in accordance with the growing period and consisting mainly of grain components of local production. The broilers of the experimental group have been fed the same compound feed, but with the addition of two enzyme drugs Sanzyme and Sanfyse 5000 (100 g/t of feed) as well as lecithin (10 g/kg of feed). The results of the production experiment fully confi rmed the data obtained in the scientific and economic experiment. The positive effect of the joint use of the studied enzyme drugs and lecithin has been manifested in all the studied productive traits. In particular, the increase in live weight of broilers increased by 12,1 %, slaughter yield by 3,5 %, the yield of carcasses of the 1st category by 3,0 %. The main economic indicators also found their confirmation: feed consumption per unit of growth decreased by 11,7 %, additional profit was received in the amount of 27308,2 rubles, the level of profitability of broiler rearing increased by 18,4 %.

Effect Of Feeding

The results of the effect of feeding the chelated form of Zinc on the safety, productivity and slaughter parameters of broiler chickens are presented. The aim of this study was to determine the safety, productivity and slaughter parameters of broilers on the background of feeding chelated form of Zinc. Materials and methods. Experimental studies were conducted during 2020 on broiler chickens cross Cobb-500 in the vivarium of the Veterinary Faculty of Sumy National Agrarian University (Ukraine), divided into two groups on the principle of analogues (control and experimental) of 50 broilers each. The source of zinc for chickens in the control group was their sulfates. Chelated forms of Zinc were used for broiler chickens of the experimental group. All groups of broiler chickens were administered the compound with compound feed in a dose that corresponded to the daily requirement of the bird in this trace element. The duration of the experiment is 42 days. The growth and development of broilers were evaluated on the basis of determining the relevant zootechnical indicators. Live weight of birds was determined by individual weighing on scales of the VNC type with an accuracy of ±1 g at the age of 7, 14, 21, 28, 35 and 42 days. Both scientific and economic experiments also determined the preservation of livestock - daily by the number of culled and dead birds. Feed consumption was recorded daily, for each week of cultivation and for the entire period of the experiment. At the end of the experiment, the cost of feed per 1 kg of live gained weight was calculated. Results. According to the results of the conducted researches, it was established that feeding of the chelated form of Zinc probably increased both the average daily gain and the total live weight of broiler chickens at different age periods of rearing. The live weight of chickens at the beginning of the experiment was almost the same, but at 7 days of age it tended to increase in chickens of the experimental group, although a significant difference between groups in this indicator was not found. It was found that the weight of uneviscerated, semi-eviscerated and eviscerated chicken in poultry of the experimental group was greater than similar indicators in the young animals of the control group by 9.3, 9.2, and 9.8 %, and this difference was significant (p<0.01). The yield of semi-eviscerated carcasses was higher in ones of the experimental group (84.19 %), and the difference was significant (p<0.05). Conclusions. It was found that the live weight of chickens of the experimental group (consumption of feed with a chelated form of Zinc) prevailed at 7 days of age by 1.1 g; on the 14th day – on 22.1 g (p<0.01); at 21 days – 35.4 g (p<0.01); at 28 days – 94.5 g (p<0.05); at 35 days – 133.6 g (p<0.01); at 42 days – at 218.9 g (p<0.05). Preservation of young animals in the experimental group, which used chelated compounds of Zinc, was higher and amounted to 96 %, compared with the control – 92 %. By age, feed costs per unit weight gain were lower in the experiment, respectively: 0.05; 0.08; 0.12; 0.06; 0.07 and 0.05 kg, compared to the control group. Growing broiler chickens on compound feed with a chelated form of Zinc by 9.8 % (p<0.01) increases the weight of the eviscerated carcass.

The aim of this study is to investigate the effects of adding different doses of boric acid (H3BO3) to the mixed feed of Japanese quail (Coturnix coturnix Japonica) on fattening performance, carcass and bone properties. For this purpose, a total of 96 quails aged 15 days were balanced according to their live weight and sex, and 4 trials were randomly divided into groups. Each group is composed of 4 repetitions. Trial groups; the control group (C) given mixed feed, the group with 100 mg / kg boric acid (BA) added to the feed BA100; 300 mg / kg boric acid was added to the feed group BA300 and 500 mg / kg boric acid added to the feed group BA500. Data for the fattening period were followed for 15-43 days. At the end of the experiment, carcass and bone characteristics of 8 quails (two quails from each repeat) from each group were examined. The live weight and live weight gain of the quail was similar among the experimental groups (P>0.05). Adding boric acid to feed did not affect feed consumption and feed utilization rate (P>0.05). While the breast rate decreased significantly due to the increasing levels of boric acid addition (P<0.01), an increase in the back and neck ratio was detected (P <0.05). The highest thigh ratio was found in BA300 and BA500 groups (P<0.05). Carcass yield, wing and liver rates were similar between the groups (P>0.05). Tibia and femur weights and dimensions were not affected by the addition of boric acid (P>0.05). The highest femoral ash level was determined in the BA300 group (P=0.05). The tibia ash level increased from the Control group towards BA300 and was the lowest in the BA500 group (P<0.05). As a result, while the addition of boric acid to the feed cannot be affected to the fattening performance of quail, its effect on carcass and bone properties has been found significant.

The development of industrial poultry farming requires not only the breeding of new highly productive poultry breeds, but also the development of new rearing technologies and the improvement of standardized nutrition. Currently, in the field of feeding farm animals and poultry an important research area is the search for cheaper non-traditional and affordable feed products that can replace part of the grain in the poultry diet. It is very important to use local raw materials. One of these crops is naked oat, which has the highest energy content, the highest concentration of lysine and methionine among all cereals. The purpose of the researches was to determine the eff ectiveness of using naked oat in compound feed for quails. The results of the influence of complete nutrient-balanced compound feeds with naked oat on zootechnical and economic indicators in the rearing of quails have been presented in the article. It has been found that the live weight of quails in the experimental group has been increased by 3,06 %, while the average daily feed consumption has been increased by 1,83 %. Feed expenditures per 1 kg of live weight gain in the experimental group have been lower by 1,31 % due to the absorption of feed nutrients. According to the results of the balance experiment, the digestibility of raw protein has increased by 1,90, fat by 0,41 %, nitrogen-free extractive substances by 2,77 %. When calculating economic indicators, it has been found that the use of naked oat in compound feed for quails allowed to increase the yield of meat and revenue from its sale by 3,75 %. Despite an increase in the total cost of feed consumed by the experimental group by 2,27 %, the profi t has been received by 9,59 % more. The level of profi tability of quail meat production in the experimental group exceeded the indicator of the control group by 3,40 %.

The purpose of the researches was to study the influence of different doses of smectic kizelgur and calf skim milk replacer in the recipes of compound feed for young pigs under the conditions of industrial pork production technology. The experimental part of the work has been performed under the conditions of the pig complex of LLC “BMPK” in the Karachevsky area in the Bryansk region. The research materials were compound feed for young pigs on fattening in the inclusion of different doses of smectic kizelgur. The infl uence of feeding compound feed with different doses of smectic kizelgur and calf skim milk replacer to young pigs on productivity, digestibility of nutrients and use of nitrogen, morphological and biochemical parameters of blood, fattening and meat traits of young pigs has been studied. Effective recipes for feeding compound feeds to young pigs prepared with the inclusion of different doses of smectic kizelgur and calf skim milk replacer have been identified. The data have been obtained from the first experiment of young pigs when them fed compound feed with different doses of smectic kizelgur; it has been followed that at the end of fattening the biggest live weight of gilts had in the 4th experimental group fed compound feed, which included 3 % smectic kizelgur. The influence of the additive on changes in live weight and daily gains when adding smectic kizelgur to compound feed in doses of 1,5 and 2,0 % was less, but the trend to increase these indicators over the period of fattening has remained. In the second experiment young pigs have been fed by compound feed, which included different doses of smectic kizelgur and calf skim milk replacer the average daily gain in live weight was higher in the 3rd experimental group, where they fed compound feed with the addition of 2,5 % smectic kizelgur and 2,5 % calf skim milk replacer by 2,2 %, than in the control group. The highest efficiency has been also obtained in the 3rd experimental group, where the monetary revenue has been received by 2160 rubles more in comparison with the control group of pigs.

Under the environments of the Tyumen region a scientific and research work has been carried out, including an assessment of the influence of antimicrobial substances: colloidal silver, antibiotics and organic acids on the body of broiler chickens. The purpose of the work was to evaluate the influence of antimicrobial substances on the productivity of broiler chickens. The research and laboratory experiment has been carried out in the laboratory of the Northern Trans-Ural Scientific and Research Institute of the Tyumen Scientific Center of Siberian Branch of Russian Academy of Sciences on chickens of the cross ArborAykrs+. Chickens at the daily age have been distributed according to the principle of balanced groups-analogues. The period of chicken rearing was 35 days, during the same period the analysis of the studied antimicrobial substances has been performed. The composition of the test substances was included colloidal silver 10 μg/l, antibiotics (Pulsoceril, Enronite) and the mixture of organic acids (Agrofeed) at the dose of 0,4 ml/l. The results have shown that chickens that have been watered colloidal silver had the gain of live weight for the period of rearing 1850,94 g or lower than chickens in the control group. At the same time, broiler chickens with watering of antibiotics and organic acids exceeded the control group’s analogues. For example chickens of the 1st experimental group where colloidal silver has been watered at the dose of 10 mcg/l every day had the live weight gain during the rearing period lower by 15,56 g and the average daily live weight gain of 0,45 g than chickens of the control group. At the same time broilers of the 2nd experimental group (with antibiotics) and the 3rd experimental group (with organic acids) had the higher gain of live weight during the rearing period by 56,61 and 95,23 g, respectively, compared to the control group. The average daily gain diff erences were 1,62 and 2,72 g. Indicators of morphological and biochemical composition of blood of experimental groups of broiler chickens indicated that they were within the limits of the corresponding physiological norms. At the same time, there were some changes on the part of both red and white blood, which seems to be related not only to the body’s response to feeding, but also to the biochemical processes within the body.
